Atlantic bluefin tuna is a commercially and ecologically important fish. Although Pacific-wide populations are well below target levels, U.S. wild-caught Pacific bluefin tuna is a smart seafood choice because it is sustainably managed under rebuilding measures that limit harvest by … Pacific Bluefin Tuna. Tunas can elevate their red (slow-twitch, oxidative) skeletal muscle, visceral and cranial temperatures significantly above the ambient water temperature (Ta) with the aid of specialized blood vessels (retia mirabilia) that conserve metabolic heat. The tuna's ability to maintain body temperature has several definite advantages over other sea life. The next update is planned on or before 15 October 2018. More on authors: Temminck & Schlegel.
